Stripe today announced its first major update to Stripe Checkout, its attempt at the most straightforward payment experience possible. The new release includes expanded address support, optimizations for more devices, and an option to save payment info.

First, expanded address support means three things: revamped address handling (support for separate billing and shipping addresses), streamlined entering of addresses (automatically selects the user’s country, fills in their city and state when they enter a postal code), and support for integrated billing address verification (users are told if they mistype something). The first was one of the most common feature requests, according to Stripe, while the other two are just overall improvements.

Next up, Stripe has made more device optimizations, claiming it has redesigned Checkout from scratch for every device. Checkout supports Android, iOS, Windows Phone, OS X, and Windows, so you can use it regardless of whether you’re on a phone, tablet, or desktop.

Last but not least, Stripe has added a new “Remember me” checkbox that allows users to save their payment info by providing a mobile phone number. Stripe promises it securely identifies users via text message so they don’t have to retype their payment information or remember an additional password.

The startup promises this results in a “rapid checkout experience” on any site using Checkout:

We’ve been testing this for the past couple of months—our hypothesis was that it would increase conversion rates—and we’re delighted that it has been confirmed. In a recent test, a customer with their details saved was several times less likely to abandon their purchase than one without.

If this sounds right up your alley, you’ll want to check out the updated documentation. Checkout has come a long way since it arrived in January 2013.
